Un problème de strip-packing stochastique

François Clautiaux, Said Hanafi, Ya Liu, Christophe Wilbaut

Dans ce résumé nous nous intéressons au problème de strip‐packing en deux dimensions et à deux étages, dans lequel il existe une incertitude (ou erreur) sur la taille des articles. Nous proposons plusieurs modélisations de ce problème, ainsi que des heuristiques constructives et d'amélioration…

Minimisation des pénalités d’avances et de retards sur une machine

Rachid Benmansour, Said Hanafi, Rita Macedo, Mustapha Ratli, Christophe Wilbaut

Les problèmes d’ordonnancement sont très étudiés par la communauté de la recherche opérationnelle en raison de leur forte présence dans l’industrie. Le concept du juste‐à‐temps avait comme motivation principale l’élimination des gaspillages à tous les niveaux; l’importance de ce concept a conduit à…

The control of myopic behavior in semi-heterarchical production systems: A holonic framework

Gabriel Zambrano Rey, Cyrille Pach, Nassima Aissani, Abdelghani Bekrar, Thierry Berger, Damien Trentesaux

Heterarchical control architectures are essentially founded on cooperation and full local autonomy, resulting in high reactivity, no master/slave relationships and local information retention. Consequently, these architectures experience myopic decision-making, bringing entities towards local…

An agent-based framework for supply chain cooperation

Mourad Abed, Benaissa Ezzeddine, Abdellatif Benabdelhafid, Janusz Grabara

The importance of cooperation in the supply chain has led scholars to suggest diverse approaches for problems in the collaboration process. Cooperation refers to the integration of different parts of an organization or different organizations in supply chain to accomplish a collective set of tasks…

Deployment of a fully distributed system for improving urban traffic flows: A simulation-based performance analysis

Philippe Thomin, Alain Gibaud, Pierre Koutcherawy

Distributed, cooperative systems dedicated to road traffic self-organization are very attractive, but present some drawbacks. In particular, their cooperative nature makes them fairly inefficient when working with a reduced number of partners. This situation typically corresponds to the deployment…

Identification of Johnson-Cook's Viscoplastic Model Parameters Using the Virtual Fields Method: Application to Titanium Alloy Ti6Al4V

Delphine Notta-Cuvier, Bertrand Langrand, Eric Markiewicz, Franck Lauro, Gérald Portemont

The identification of viscoplastic material parameters is addressed using a new powerful method: the virtual fields method (VFM). Contrary to classical procedures that are statically determined, the VFM is applied to heterogeneous mechanical fields. Without any hypotheses of homogeneity required,…

Classes de Steinitz dʼextensions galoisiennes à groupe de Galois de centre non trivial

Bouchaïb Sodaïgui

Let k be a number field and Cl(k) its class group. Let Γ be a finite group and |Γ| its order. Let R(k, Γ) (resp. R m(k, Γ)) be the subset of Cl(k) consisting of those classes which are realizable as Steinitz classes of Galois extensions (resp. tamely ramified Galois extensions) of k with Galois…

Measuring the 2D residual surface stress mapping in tempered glass under the cooling jets: the influence of process parameters on the stress homogeneity and isotropy

Yuan Chen, Dominique Lochegnies, R. Defontaine, J. Anton, Hillar Aben, R. Langlais

In glass products, thermally tempered on industrial lines for automotive and architectural industries, the distribution of residual stress is highly inhomogeneous and, in certain situations, can produce optical defects that are more visible in sunlight because of the impact of the cooling jets on…

On Some Holomorphic Cohomological Equations

Aziz El Kacimi Alaoui

Let Σ be a non compact Riemann surface and γ:Σ⟶Σ an automorphism acting freely and properly such that the quotient M = Σ/γ is a non compact Riemann surface. Using the fact that Σ and M are Stein manifolds, we prove that, for any holomorphic function g:Σ⟶C and any λ∈C , there exists a holomorphic…
